Hi Wayne,
I tried your issue with GdGetTextSize() and get a result.
I compared the widths I get from GrGetTextSize() and GrGetFontInfo() => different widths.
For my problem: I use both functions in combinition to get the info I need.
Many thanks.
But only for interest: Why is it so?
merry christmas and a happy new year 2014
Andreas

It looks like you are using the nano-x wrapper around the graphics engine.
We don't use that portion of the code so I don't have it in my source tree
at the moment. I would look for this function in the nano-x wrapper code
to see if it used. From there you can figure out how it is exposed.
